Fertilisers for vineyards: what to consider
Boron, iron, potassium and biostimulants: pointers for vineyards, from the data sheets.
Vines have their own nutritional needs throughout the cycle, from budburst to ripening. This guide lists the products in the range sold by Fertipower that may be of interest in the vineyard, with caution: the data sheets describe general uses and are not specific to this crop.
What is a fertiliser for vineyards
There is no single fertiliser for vineyards. Vine nutrition combines soil fertilisation, based on soil analysis and the condition of the foliage, with targeted interventions, often foliar, to correct a deficiency or support a sensitive stage. Flowering, fruit set and ripening are stages when the availability of certain elements matters more.
Product choice should start from a diagnosis: soil analysis, observation of the leaves and, where necessary, leaf analysis. The products below meet needs that the data sheets describe for a wide range of crops and that also arise in vineyards.
When to use them
- Flowering and fruit set: the Folibor-k data sheet links boron to better flowering and fruit set and to pollen germination.
- Crop quality: Folibor-k is intended in particular for situations where nitrogen or sodium could adversely affect the sugar content of crops.
- High-pH soils: the Sanbor data sheet notes that a high soil pH blocks the availability of boron.
- Signs of chlorosis: the Fersol 20 data sheet states that iron helps to prevent chlorosis and premature leaf fall.
- Peaks in demand or weak root development, situations mentioned in the Ligno data sheets.
Fertipower products
- FOLIBOR-K: boron with potassium, free of chlorides, sulphates and nitrate or ammonium nitrogen; the potassium improves the uptake and use of boron and supports functions such as flowering, fruit set and late translocation of sugars.
- Sanbor: highly soluble formulation to prevent and correct boron deficiencies, applied to the leaves or through the irrigation system.
- Fersol 20: highly soluble formulation to prevent and correct iron deficiencies, applied to the leaves or to the soil.
- LIGNO MIX: to prevent and correct micronutrient deficiencies in a wide range of agricultural and ornamental crops.
- Vitta K Express: high potassium content, formulated with bicarbonates; according to the data sheet, potassium supports carbohydrate synthesis and increases sugar accumulation.
- AlgiPower (1KG): seaweed extract (Ascophyllum nodosum); according to the label, 3.5% P2O5 and 16% K2O (dry matter), for foliar application or fertigation.
For applying liquid fertilisers, Fertipower also offers sprayers, such as the Aquamix 1.25 V, 0.2% / 0.5% / 1.0% / 2.0%, whose rotary switch lets you adjust the amount of fertiliser.
Frequently asked questions
Were these products developed specifically for vines?
No. The data sheets describe uses on a wide range of crops. The choice for vineyards should start from soil analysis, the condition of the foliage and the technical data sheet of each product.
What role does boron play?
According to the data sheets, boron is essential for pollen tube germination and seed formation, and is linked to flowering and fruit set.
Can I apply through the leaves and through the irrigation system?
It depends on the product. Sanbor and Fersol 20 can be applied to the leaves or through the irrigation system; the Ligno formulations are intended primarily for foliar application.
What time of day should I apply?
The Sanbor data sheet states that optimum humidity and temperature conditions are met, in most cases, early in the morning or at the end of the day.
